There are many studies on the biomechanics of the long jump, but few researchers have investigated how the athlete has to perform the last strides in order to prepare for takeoff. In this investigation, a pattern recognition approach was applied to analyze the movement structure during the last strides of the approach run and the jump. Time-continuous kinematic data of 57 trials (4.45–6.84 m) w...

The aim of this study was to investigate the influence body composition on motor abilities in handball players. sample involved 16 male players aged 15-20. Body variables included mass (BM), index (BMI), percentage fat (PBF) and muscle (PMM). For speed assessment, 20m sprint test used. T-test, Slalom Zig-Zag were used estimate agility, while squat jump (SJ), counter movement (CMJ) with arm swin...

Though popular, there is little agreement on what whole-body vibration (WBV) parameters will optimize performance. This study aimed to clarify the effects of age, sex, hertz and time on four physical function indicators in community-dwelling older adults (N = 32). Participants were exposed to 2 min WBV per session at either 2 Hz or 26 Hz and outcome measures were recorded at 2, 20 and 40 min po...

The amount of training days lost to injury during military training has highlighted the need to identify a screening tool to predict injury. One hundred and fifty-eight female soldiers from the Combat Fitness Instructor Course (CFIC) of the Israel Defense Forces volunteered to participate in this study. All soldiers were free of orthopedic and neurologic conditions for at least one month before...

BACKGROUND The efficacy of wearing [a] compression garment (CG) between repeated bouts of exercise within a same day has not been fully understood. The present study determined the effect of wearing a CG after strenuous exercise sessions (consisting of sprint exercise, resistance exercise, drop jump) twice a day on exercise performance, muscle damage, and inflammatory responses. METHODS Eleve...

Knee stability during a functional assessment of the stop-jump task is a key factor to determine if an athlete is adequately rehabilitated after knee ligamentous injury. This study aimed to investigate knee stability due to the effect of anticipation on landing maneuvers during planned and unplanned stop-jump tasks. Knee kinematics of ten healthy male participants were collected using an optica...

Despite the inclusion of beach volleyball as an Olympic discipline with a fully professional world tour, little research has been published that has examined the physical qualities of internationally competitive athletes. Thirty international-standard beach volleyball athletes (14 male, 16 female) performed countermovement jumps (CMJ) and squat jumps (SJ) on a force platform. Ground reaction fo...

The purpose of this study was to determine if wearing graduated compression tights, compared with loose fitting running shorts, would increase and or help sustain counter movement jump (CMJ) height after submaximal running. Fourteen competitive runners (6 women and 8 men) participated in this study. The subjects' mean (±SD) for age, height, body mass, percent body fat, resting heart rate, and m...

The purpose of the investigation was to determine the relative oxygen consumption (VO2), heart rate and oxygen pulse associated with the constituent elements of an exercise-to-music class. Six women exercise-to-music leaders with a mean(s.d.) age, weight and height of 33.2(5.2) years, 51.0(2.8) kg and 157.9(5.6) cm respectively, completed five distinct exercise-to-music movement elements. The m...
